Portable non-tuned half-wave antenna NoTune End Fed Half Wave Antenna Half-wave antenna

The single-band 80m-10m end-fed half-wave linear antenna provides the antenna. It is designed as a highly portable wired antenna that can be easily set as a inverted V, horizontal, inclined or vertical radiator (at higher frequencies). The feed line is essentially balanced, so a separate feed line is not required. The high-impedance half-wave line is matched to your 50-ohm feed point through an integrated impedance-matching ring transformer, with a rated power of 10 watts. Using a high-voltage capacitor on the primary of the transformer with a specific radiation body length, it further expands and reduces SWR within the 80m-10m range. It is designed to be used without a tuner and, after optimizing the driving element, the SWR of any part of the band is 1.2.
